To all whom it may com-em:

Be it known that 1, WILLIAM CLAYTON CoRYhLL, citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Building Fabrics, of which the following is a specification.

This invention relates to building material employed chiefly as a substitute for wooden and metal lathing and particularly to a building material or fabric of that character having a novel form and novel reinforcement which materially improve the structural and functional characteristics thereof.

Certain important objects are achieved by the present invention. Among these objects are primarily to provide a building material or fabric of a cheap and simple construction and which shall be available generally as a form or matrix for plastered walls, partitions, ceilings and other portions of a building, as well as susceptible of being used alone as a panel material. Also, it is proposed to provide a material or fabric of such structural conformation as to provide an effective and extensive keying surface for receiving and holding the wall plaster, stucco, cement or other surfacing material. Furthermore, it is also an important object, of the invention to construct the new building material in such form as to facilitate admitting of a very effectual disposition of reinforcing elements which not only contribute to the stiffening and strengthening of the product itself, but which also will azdord asubstantial reinforcement and support for the cementitious material when hardened Another object of the invention is to con struct a building material or fabric in which the expansion and contraction will be, so little as to be a negli 'ble consideration,

and also to embody wit the material during its manufacture elements or means which will render the same both waterproof and fire-resistant, and which will not be subject to-warping whenthe wet plaster is ape With these and other objects in view which will readily appear to those familiar with this art as the particular featuresof Though susceptible of a wide range of modification as to essential features, a few preferredand practical embodiments of the invention are shown in the accompanying drawings, in which Figure 1- is a plan view of a building fabric embodying the present invention.

Fig. 2 is an end edge view of the fabric unit shown in Fig. 1.

Figs. 3 and i are cross-sectional views of the fabric respectively on the lines 33 and 4'4g of Fig. 1.

Fig. 5 is a side edge view of a piece or unit of fabric shown in Fig. 1.

Figs. 6 and 7 are longitudinal sectional views of the fabric respectively on the lines 66 and 7-7 of Fig. 1.

Fig. 8 is a plan view of a panel form of the fabric or material in which the keying openings through the sheet are omitted.

Like references designate corresponding parts in the several figures of the drawings.

A building material or fabric constructed in accordance with the present invention primarily includes, in combination, a novel consolidation of, metallic reinforcing and holding members for the plastic or equivalent material with a flexible body sheet or element carried with said members. A structure of this kind is available see substitute for wooden and metallic lathing and possesses several advanta es thereover, principal among which are c -eapness and simplicity of manufacture and the adaptability of such a material to the use of metallic reinforcement which effectually reinforces the Wall and constitutes permanent supporting elements therefor, at the same time contributing materially to an effectual keying of the plaster onto the body sheet. Furthermore, a consolidation of the flexible body sheet and the metallic members in the material contemplated by the present invention provides afabric which can be made to respond to all building requirements for such a material.

The flexible body sheet or element, forming a part of the present invention, is designoted in the drawings by the numeral 1 and this is preferably a fibrous material made impervious to water by being impregnated with a suitable waterproofing compound such for instance as silicate of soda and asphaltum or other known. waterproofing substances. A sheet material of this kind and character are the well known commercial roofing papers, but it would of coursebe understood that in carrying forward the invention any equivalent material could be utilized, though the preferable embodiment of the invention includes a flexible sheet of fibrous material given suitable treatment to render the same substantially waterproof and therefore resistant to the warping influence of the wet plaster. Also it is preferable to prepare the flexible body sheet in such a manner as to render the same fireresistant as well as to afford better adhesion between the fabric and the plaster. This may be accomplished by various expedients one of which would be to surface the sheet, before the same is ready for use, with an earthy or non-combustible substance as for instance by rolling or otherwise pressing fine sand, dust or equivalent dry granulated material into the surface, and subsequently dipping the sheet into a liquid form of artificial stone thereby producing an artificial stone-like surface on the fabric. Any well known artificial stone composition may be employed for this purpose, such as a mixture of silicate of soda, infusorial earth and oxid of ZlIlCr Furthermore, in the preparation of the flexible body sheet or element it is desirable, under certain conditions, to accelerate, the drying of the surfacing liquid and while different expedients obviously could be resorted to for that purpose a simple and effective method proposed is to sprinkle dry noncombustible dust against the wetted surface, causing the dust to adhere to such surface and naturally hasten the drying thereof. This treatment, moreover will to some extent increase the stone-like appearance of the fabric as well as thicken the non-combustible coating or surface over the combustible material of the fabric.

It is regarded as desirable, as indicated, t prepare the body sheet so as to make the same waterproof and fire proof and also not subject to warping when the wet plaster is applied, but the distinctive and important structural characteristic of the invention is the novel manner in which this body sheet is consolidated or combined with the metallic reinforcing and holding members. These metallic members or strands may consist of metal wires, rods or strips of any suitable gage according to the weight and stiffness required for the materiol or fabric in the particular building operations for which it may be specified. But, regardless of the size and form of the metal wires, rods or strips the same are interwoven with the body sheet plished in any suitable manner by machi-ncry or otherwise, but the operation necessarily involves what may be termed threading of the metallic members through the sheet from end to end or side to side thereof according to the form and dimensions of the sheet.

However, for illustrative purposes there is shown in the drawings a fabric unit embodying the novel reinforcement, that is, a piece or section of fabric made in accordance with the present invention. Referring to this unit of construction shown particularly in the group of Figs. 1 to 7 inclusive it will be observed that the flexible fibrous body sheet 1 may be provided with a plurality of rowsof threading holes 2, the series of holes in each row being in longitudinal alinement and being adapted to have a metallic reinforcing member 3 woven or threaded therethrough so that portions of the reinforcing member will be alternately disposed upon opposite sides of the body sheet with the result of giving the uniform reinforcement throughout the fabric, as well as making the latter reversible so that the plaster coat may be applied to either side thereof;

The weaving or threading of the individual metallic reinforcing members 3 through the row of holes provided therefor involves certain structural features which are of practical importance. In the first place it will be observed from the groupof Figs. 2 to 7 inclusive that the flexible body sheet is given a crimped formation, forming shallow undulations laterally of the sheet shown in Figs. 2, 3 and 4, and producing, in. the longitudinal plane of the reinforcing members 3, a corrugated effect. This corrugated, effect provides within the longitudi nal plane of each reinforcing member, upon opposite sides of the sheet, the depressions or sinks t within which lie the exposed portions of the reinforcing members. This is plainly shown in Fig. 6 of the drawings and from that figure it will also be observed that the peculiar. crimped formation described has the efiect of bringing the threading holes of each row into longitudinal alined communication so'that the reinforcing wire or rod may be threaded in a straight line therethrough, and may bev maintained straight in order to have its full efliciency as a reinforcing member as well as facilitatmg the operation of manufacturing the fabric.

Although the threading holes have been referred to as a desirable means to facilitate the weaving of the reinforcing members through the body sheet it is to be understood that my invention is not limited to this detail of construction because the same structural result can be accomplished by merely slitting the sheet at the locations of the holes 2 or by employing a sharpened reinforcement as indicated at m in Fig. 6 which could readily pierce through the sidewalls of the corrugations referred to, as may be plainly seen from the said Fig. 6 of the drawings.

. In addition to the advantages afforded in the manufacture of the improved fabric by crimping the body sheet and weaving or threading a reinforcin member or members therethrough, it wi 1 be seen from Fig. 6 of the drawings that the depressions or sink 4 inwhich the exposed portions of the reinforcing members he constitute seats in which the wet plaster locks itself on or about the reinforcement, thus contributing quite materially to the effective keying of the plaster coat onto vthe fabric. This keying of the plaster coat to the fabric may be materially increased by providing the fabric at suitable intervals therein, preferably alternately with the rows of reinforcements 3,

with a plurality of keying openings 5 constituting keying elements through'which the lugs of plaster extend. For this phase of the invention any equivalent supplementary keying elements ,or means may be utilized to supplement or insure the adhesion of the plaster or surfacing material to the fabric.

It will of course be understood that'the herein described fabric or material may be rendered available for use as acheap panel construction by simply preparing the same with the threaded orwoven reinforcements without keying openings or equivalent expedients associated 'with the sheet. This is illustrated in Fig. 8 of the drawings.

From the foregoing it.,is thought that the construction, use and advantages of the herein described building fabric or material will be readily apparent to those familiar with this subject without further description but it will be understood that changes in the form, proportion and minor details of construction may be resorted to without departing from the principle or-sacrificing any of the advantages of the invention.
